Last year, we forecast that 30% of all retail paid-search spend would be on a shopping ad, and 45% of all product ad clicks would be on a smartphone—and smartphone click growth ended up being even stronger than we predicted. Looking forward, where do we see shopping ads this holiday season?

We took a look at month-over-month variations and factored in seasonal shifts in performance to forecast where we’ll be by December 2016:

40% of all shopping ad dollars will be on a smartphone

37% of paid search clicks will be on a shopping ad

Social clicks and spend share should flatten out over the year and remain at current levels
